Start with the exact vehicle application

A projector headlight assembly should be selected by exact vehicle fitment and lighting configuration, not by appearance alone. Two housings can look similar yet differ in mounting tabs, connector pinout, beam orientation, control modules, or market-specific compliance. Feng Cheng describes its product as a clear-lens projector headlamp with a precision-molded housing and factory-style beam pattern, and says platform coverage includes Japanese, Korean, GWM/HAVAL, and ZTE vehicles. The company also states that compatibility is confirmed for the specific model, so a buyer should submit the vehicle make, model, and year before ordering.

The first fitment record should identify model year, make, model, trim or submodel, body style, market, and left- or right-hand drive. Include the vehicle identification number where appropriate, the original equipment part number, and clear photographs of the front label, rear connector, mounting points, and beam-side markings. These details help distinguish refresh years and trims that share a model name but use different lamp shapes or electrical systems. A marketplace description such as ‘fits 2018–2021’ is not adequate unless it matches the vehicle’s exact version and the supplier confirms it in writing.

Use a six-field fitment record for each requested SKU: vehicle identity, OE reference, side, traffic direction, light-source and connector configuration, and included functions. Attach one photo of the existing lamp label and one rear-view connector photo. A supplier can then confirm the exact part number and list any reused modules or coding requirements. Keep that confirmation with the purchase order so receiving inspectors can compare the delivered box and assembly against the approved record.

Company-published operating context from Feng Cheng’s homepage

These figures are published by Feng Cheng and are not independently audited in this article. Confirm current figures, part-specific capacity, delivery basis, and order lead time in the quotation. Product-level vehicle fitment remains order-specific.

Confirm side, functions, and source type

Next, specify the side and complete lighting function. State left-hand or right-hand assembly using the convention expected by the supplier, then confirm driver-side/passenger-side for the target market. Ask whether the assembly includes low beam, high beam, turn signal, daytime running light, or position lamp functions, and whether bulbs, modules, adjusters, and wiring are included. Feng Cheng’s public page identifies a factory-style connector layout and a precision projector lens but does not publish a universal connector pinout or a model-by-model catalog. Treat those details as order-specific until documented.

Light source and electrical architecture must match the vehicle and local rules. A projector optic is a beam-forming component; it does not tell a buyer whether the assembly is halogen, LED, HID, or an integrated design. Request the specified source type, rated voltage, connector diagram, control unit requirements, and any bulb specification. NHTSA explains that FMVSS No. 108 regulates headlighting systems [3] and that replacing or altering a system with an incompatible source can create a compliance problem. In the United States, DOT marking reflects the manufacturer’s certification, not a separate NHTSA product approval.

Check traffic orientation and market rules

Beam orientation matters when a vehicle crosses markets. A headlamp designed for right-hand traffic may have a different low-beam cutoff pattern from a unit designed for left-hand traffic. Confirm traffic side, optical aim, and required market approval before shipment. Do not assume that a mechanical fit means legal or optical fit. For fleet or export programs, obtain the supplier’s compliance documents for the exact part number, target jurisdiction, and light-source configuration. The applicable regulation depends on destination; U.S. FMVSS No. 108 is not a substitute for checking other national or regional requirements.

Verify housing interfaces before ordering

Physical fit should be verified against reference dimensions and interfaces. Check overall lens shape, housing depth, mounting-point coordinates, adjuster locations, vent positions, rear cover clearance, and harness routing. Confirm whether the vehicle needs an adapter, module transfer, coding, or calibration. Feng Cheng says the lens is impact-resistant polycarbonate and the housing is sealed for moisture and dust resistance, but the page does not specify dimensions, material grade, ingress-protection rating, or durability test results. A buyer can ask for drawings, sample photographs, validation records, or a physical sample instead of inferring a specification from marketing terms.

Protect the approval through purchasing

For an aftermarket replacement projector headlight assembly, preserve documentation from the quote through receiving inspection. The purchase order should include the confirmed vehicle application, side, source type, connector and included components, market, marking requirements, packing, and defect process. If a sample is approved, label it with the supplier part number and revision. At receiving, compare labels and mounting interfaces against the approved sample; do not mix a visually similar but unverified revision into a production or service batch.

A short fitment workflow lowers avoidable returns: collect vehicle data, validate the OE reference, confirm the lamp’s source and functions, verify the market and beam orientation, then review drawings or a sample. That is especially valuable for wholesale buyers sourcing projector headlight assemblies for multiple vehicle platforms. Feng Cheng presents dedicated lighting lines and fitment review as part of its supply process, but each application should still be confirmed as a specific part-to-vehicle match. Exact written confirmation is the key control point.

Frequently Asked Questions

Does “projector” identify the bulb type?

No. Projector describes an optical arrangement. Confirm whether the assembly is designed for halogen, LED, HID, or another specified light source and verify its electrical requirements.

Is DOT marking an approval by NHTSA?

NHTSA says DOT marking indicates the manufacturer’s certification of compliance; it is not a separate NHTSA approval label.

What should I send for fitment confirmation?

Provide make, model, model year, trim, market, left/right drive, OE number, photos of labels and connectors, and the desired lamp side and functions.
